Specification of Letters Patent. Patented lVIar, 9. 1920,

Application filed December 21, 1917. Serial No. 208,227.

f0 all'whom it may concern:

Be it known that-I, ALVA J. FIsHER, a citizen of the United States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Ironing-Machines,

of which the following is a specification.

My invention relates to an ironing machine and to the roll thereof andthe'object thereof is to provide for such roll a. pad of a certaincharacter offibrous material such as jute, whereby .the numerousobjections heretofore experienced in practical use with pads of othermaterial are efl'ectually overcome.

In practice pads for ironing machines are made of felt, such ascotton,.wool or hair felt, but all of these materials are open toobjection. For instance, the cotton felt, owing to the heat and dampnessacting upon it becomes very'hard and dense inasmuch as it holds themoisture coming from v the clothes being ironed and ina short timebecomes practically a solid roll. A roll of seven inches in diameterwillshrink to about six and one-half inches owing to the fact that thepad becomes packed solid.

In case of wool felt, the thickness thereof is about three-sixteenths ofan inch as ordinarily used for this purpose and owing to this thicknessthere are only about five laps or thicknesses on a roll. As a result thefirst lap and the last lap cannot meet within about-two inches.otherwise there would be a ridge the entire length of the roll due tothe fact thatat this particular point there would be six laps orthicknesses instead of five. Sometimes the ends of'the pads will overlapunintentionally and in this event the roll will not do satisfactory workas it will scorch the material where the ridge exists, or they clotheswill not be thoroughly ironed inasmuch as the shoe isheld in contactwith springs and consequently where there is an excess thickness theshoe will be released as the ridge comes around and into contact withthe shoe. Moreover. a wool felt pad burns very easily with a little'eX-cess of heat and soon becomes discolored to adark brown besides becomingpacked very hard. This reduces the strength of the pad and will cause itto break off in pieces.

In the case of the hair felt, a pad made therefrom is not strong and theresult is much the same as in the ,case'of the wool felt, particularlyas -to becoming hard and I packed and also as to permitting of only afew thicknesses to be applied owing to the thickness of the hair feltwhich is from one quarter to three eighths of an inch. Moreover itismore diflicult to apply on the roll than either the cotton or woolfelt.

I have discovered that a fibrous material such as jute has the propercharacteristics and attributes to form a most efiicient pad inasmuch asit overcomes, all of the objections noted in respect to pads of theother materials mentioned, as well as other advantages as hereinafternoted and. as made apparent from the description of my new pad orillustration thereof in the drawmg.

In the drawing F igure 1 is a sideelevation of an ironing machine inwhich invention is embodied; Fig. 2 an end elevation thereof; Fig. 3 anelevation of the roll detached, showing the beginning of the op erationof applying the pad thereto; Fig. 4 a cross section on an enlarged scaletaken on the line 44 of Fig.3; Fig. 5 a detail elevation of a portion ofthe roll showing one of the retaining hooks; Fig. 6 a section onthe-line 6-6 of Fig. 5, and Fig. 7 a detail view of the fibrous materialemployed 'for the pad.

In Figs. 1 and 2 I .have shown the type of ironing machine to the rollof which my invention is applied. This ironing machine consists of amain frame 1 which'supports supplemental frames or end brackets 2. Inthese brackets is journaled the ironing roll 3 on whose-periphery isformed or mounted the pad 4. The shoe 5 is pressed against the pad orrather-against the clothes to be ironed which are interposed between theshoe and the pad. This pressure is a yielding one owing to the pivotalmounting of the shoe and the provision of the springs 6, the details ofwhich it is unnecessary to explain as they are of well known character.The roll 3 may be of the usual construction but I prefer to make thesame as shown in Figs. 3 and 4, providing it with a series of hooks 7arranged at intervals along the length of the roll for'the purpose of enaging the inner end of the material of W ich the pad is formed.

The material of the. pad is of the coarse woven character as shown at 8in Fig. 7,

such material in practice beingknown as jute. This material is firstapplied to the hooks of the roll and wound therearound as many times asrequired to give the necessary thickness or diameter of pad. It is foundin practice that such to its original diameter to whatever size it mayhave been built up to, which invariable diameter is of great importanceinasmuch as it provides a uniform ironing surface.

Other advantages of the jute pad are that it is impossible to burn thesame with the heat applied bythe ironing machine shoe and that thedampness coming from the clothes being ironed penetrates and escapesthrough the pores of the jute pad, with the result .that a sheet ortablecloth for instance can be ironed in about twenty-five per cent. ofthe time required when the, other kinds of pads above mentioned areused. Moreover the pad retains its original character-'.

istics particularly its pliability, so that it is not necessary as inthe case ,of the other types of pad to remove and Wash it. Furthermorethe cost ofthe jute pad is only a fraction of the cost of the otherkinds of pad.

In addition, the jute pad'Will not shrink a pad will hold which is ofconsiderable advantage inasmuch as the danger of the, burning of the padand goods being ironed is prevented. The ironing shoe being made ofmetal always retains its radius, and if he pad should shrink as happensto the old describedforms of pads, the area of contact between the shoeand pad is thereby reduced, with the result that the pressure of theshoe remaining the same the greater pressure exerted on the lesser areacauses burning of the pad. Also, the jute pad can be advantageously usedin connection with rolls having a solid or impervious surface, whereinthe only places where the moisture or steam can escape are between thetop and bottom edges of the shoe. The

jute pad permits this steam or moisture to pass through its pores and toescape 'adjacent these edges of the shoe.

I claim:

1. For the roll of an ironing machine a pad formed of jute woundtherearound to provide a plurality of thicknesses.

2. In combination with an ironing machine roll having a solid orimpervious sur-- face, a pad formed of jute and applied thereto.

ALVA J. FISHER.
